I've been using Graphite for a few months now (yay, finally works on cygwin!), and I've been really enjoying it.
The command name change will take some time to get used to, though!
I've run into a bug with 1.0 where it tries to query git for an object (something with ^tree) that it doesn't understand. I think I'm on a high enough git version, but that could be my issue.
